Calling all front E70 X5M/X6M Caliper upgrade folk, please help...

Could you please advise what caliper bolts you are using and whether there is an OEM part number for these?

I understand you need 4 in total and because 4mm spacers/washers are required between the calipers and the hubs, this potentially means using longer 4mm longer bolts than stock to bridge the gap. However, not sure if this is this the case/ strictly necessary?

Can anyone shed some light?

I've checked with Bozman, who was one of the pioneers of the X5M setup, however, his bolts were pre-supplied when he purchased the calipers, so he didn't have to source them separately like I'm having to do.
